May support feasibility in high-risk aortic stenosis; hypothesis-generating and requires validation in larger trials.
Is transapical transcatheter aortic valve implantation without cardiopulmonary bypass feasible and effective in high-risk patients with aortic stenosis?
Transapical transcatheter aortic valve implantation without cardiopulmonary bypass is a feasible, minimally invasive approach that successfully increases aortic valve area in high-risk patients with aortic stenosis.
Lichtenstein et al. (2006) studied this question.
